One thing to think about as you build your exhaust system. The whole principal of opening it up is to lower backpressure and make it more efficient. If you add glasspacks or resonators in front of your Flowmasters or your Magnaflows, the back pressure has been increased and the efficiency decreases. I gave up my flowmasters and went with the Magnaflow for a smoother sound and still has a flow characteristic of a Flowmaster.
